For number of math stick, first pattern:8
+7
2nd pattern:15
So the pattern will be:
(Diff btw 2 pattern)(n) + (diff between first patt and diff)
Therefore it is
(7)(n) + (8-7)= nth term
7n + 1 = nth term
*n=number
n=1 ( 1st pattern)
n=2 (2nd pattern)
Ans: for 100th pattern, n=100
Total needed=7 (100) +1
=701
+7
2nd pattern:15
So the pattern will be:
(Diff btw 2 pattern)(n) + (diff between first patt and diff)
Therefore it is
(7)(n) + (8-7)= nth term
7n + 1 = nth term
*n=number
n=1 ( 1st pattern)
n=2 (2nd pattern)
Ans: for 100th pattern, n=100
Total needed=7 (100) +1
=701
Not that the above method can only be used when the difference is constant.
In this case, it is by +7
In this case, it is by +7
Same goes for last part

Always remember to find the pattern. Separate the first pattern from the rest.
D) Since the number of squares = figure number. Since the answer is Figure 63, number of squares also equals to 63. Let me know if you need me to further explain.
